Like a buddy movie where two retired cops stuck in their ways have to return to active duty, these adorable bookmarks—designed to look like miniature unwound cassette tapes—work alongside antiquated printed books to help you remember what page you were last reading.

The cassette portion actually folds over the edge of a page and then clamps in place using a set of magnets, while the tape dangles down the spine so it's easy to open your tome to where you left off. Available in sets of three in various colors for just $6, they're the perfect way to tell the world that MP3s and Kindles are just too complicated for your needs. [Connect Design via Holycool]
